An Air Peace Boeing 737-300, registration 5N-BUK performing flight P4-7091 from Port Harcourt to Lagos (Nigeria) with 118 passengers and 6 crew, landed on Lagos' runway 18R at 18:33L (18:33Z) but touched down hard, rolled out and taxied to the apron.

Nigeria's AIB (NAIB) reported on Jun 11th 2019, that they were not aware of the occurrence until after a passenger reported a hard landing in on Jun 5th 2019. Investigators were dispatched to the site and found the occurrence confirmed, the right hand engine's cowling had contacted the runway surface causing damage to compressor blades of the engine, the right main landing gear oleo and strut had been fully compressed and "bottomed", the #4 tyre's (right outboard) sidewall was scoured. The aircraft had been grounded since the occurrence and is currently awaiting hard landing inspections including inspections of the wing tips, wing roots and engine pylons due to concerns over the heavy impact. The AIB accused Air Peace of concealing the occurrence from the AIB. Air Peace claimed they had reported the occurrence to the Civil Aviation Authority of Nigeria (NCAA) as well as Boeing and CFM International and had grounded the aircraft. The AIB also claims the airline had concealed another occurrence of Dec 14th 2018 involving Boeing 737-300 registration 5N-BUO and reported both FDR and CVR had been overwritten by the time the AIB learned about the occurrence. Concerning 5N-BUO the AIB had already released a preliminary report in March 2019, see Accident: Peace B733 near Enugu on Dec 14th 2018, loss of cabin pressure.

On Nov 18th 2019 the NAIB released their preliminary report stating the captain (29, ATPL, 6,250 hours total, 5,950 hours on type) was pilot flying, the first officer (33, ATPL, 3,423 hours total, 3,262 hours on type) was pilot monitoring. The aircraft was on final approach to runway 18R when tower advised the approach path to the runway was clear, however, there were thunderstorms in the the takeoff path. On 2nm final tower advised winds were from 210 degrees at 11 knots, there was a windshear alert of 60 knots on the approach path runway 18R.

The crew reported to the investigation they were #3 for landing, the two preceding approaches continued to landings, no pilot reports were made.

At 1nm final tower advised winds from 144 degrees at 34 knots. The NAIB wrote: "PF stated as follows: “I applied the required crosswind technique to keep the airplane flying towards the runway”. The PM announced for a go-around and in response, the PF said he had control of the situation."

The aircraft touched down in rain, stopped on the runway due to low visibility and vacated the runway 6 minutes later. The aircraft taxied to the apron, the passengers disembarked, only then it was discovered the aircraft had sustained substantial damage.

The NAIB listed the damage:

1. Scrapes and dents on the No. 2 engine cowling
2. Scrapes and dents on the No. 2 thrust reverser cowling
3. Some fan blades were bent on No. 2 engine
4. Both Main Landing Gears Oleo struts collapsed
5. Scuffing of the sidewall of the No. 4 main wheel tyre.

The NAIB had written in the introduction to the preliminary report:

Accident Investigation Bureau (AIB) became aware of this occurrence via phone call from a passenger onboard the incident flight on the 5th of June 2019, three weeks after the incident. AIB contacted the operator and subsequently, investigators were dispatched to the corporate office of Air Peace Limited on the 6th of June 2019, to make further enquiries.

A visit to the aircraft and subsequent evaluation revealed evidence of significant damage to the aircraft structure and its No. 2 engine. The aircraft had been declared unserviceable and grounded by the operator since the date of the incident, for further maintenance evaluation.
